About this gas system part
CMMG Zeroed Adjustable Gas Block 55DA31F is a gas system part.
Gas blocks and tubes must match the barrel's journal diameter and gas system length (pistol, carbine, mid-length or rifle). Measure the barrel at the gas port before ordering, and check that the block clears your handguard.
Manufacturer details
If you’re looking to shoot suppressed or just fine tune your AR to your preferred ammo the CMMG ZEROED Adjustable Gas Block gives you the freedom to dial in the gas system exactly to your liking.
A 20-position detent adjustment screw means you don't have so much gas that your gun beats itself up and you don't end up with too little gas to even cycle. The sacrificial cleanout chamber and user-serviceable design provides excess carbon a place to go where you can still clean it out.
Gas blocks include a 6" 3/32 hex wrench to adjust gas settings and roll pin.
